| Abstract | GRS 1915+105 is the most prominent microquasar and the most energetic object inour Galaxy. It has remained unique among its class for the large variety oftemporal behaviours in different time scales. Multiwavelength observationsshowing radio, IR and X-ray oscilations, with time delays depending on thewavelength, revealed in the past the intimate link between the accretion discand the jet ejection. However, the mechanism of jet formation and the origin ofthe delay between the flares in different wavelengths remains unclear. Here wepropose simultaneous X-ray and IR observations of GRS 1915+105 withunprecedented high time resolution, using EPIC-pn in Burst mode and VLT/ISAAC.sAladdin array in its new Burst mode, with integration times as short as 3.2ms. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
